The energy converter 54 of the second shifting device 50B includes an electric actuator or an electric motor. The electronic controller 52B of the second shifting device 50B actuates the energy converter 54B and performs shifting if the wireless communicator 56B receives an actuation command and shifting can be performed.

The front brake device 50C and the rear brake device 50D can be rim brakes, disc brakes, or roller brakes. The front brake device 50C, which is arranged on the front fork 22, stops or slows the rotation of the front wheel 12. The energy converter 54 of the front brake device 50C includes an electric actuator or an electric motor. If the wireless communicator 56C receives an actuation command, the electronic controller 52C of the front brake device 50C actuates the energy converter 54C and moves a brake shoe, a brake pad, or a roller to stop or slow the rotation of the front wheel 12. The rear brake device 50D, which is arranged on the frame 20, stops or slows the rotation of the rear wheel 14. The energy converter 54D of the rear brake device 50D includes an electric actuator or an electric motor. If the wireless communicator 56D receives an actuation command, the electronic controller 52D of the rear brake device 50D actuates the energy converter 54C and moves a brake shoe, a brake pad, or a roller to stop or slow the rotation of the rear wheel 14. At least one of the front brake device 50C and the rear brake device 50D can be actuated by a brake lever 78B of an operation device 78, which will be described later. In this case, the brake lever 78B of the operation device 78 is connected by a wire to at least one of the front brake device 50C and the rear brake device 50D.

The lamp 50E is coupled to the front fork 22 or the handlebar 24. The lamp 50E is configured to be switchable between an activated (ON) state and a deactivated (OFF) state. The energy converter 54E of the lamp 50E includes a light emitting diode (LED) or a light bulb. The electronic controller 52E of the lamp 50E switches the actuation state of the energy converter 54C if the wireless communicator 56E receives an actuation command. The lamp 50E can be configured to be alternately activated and deactivated whenever receiving an actuation command or be activated and deactivated in response to corresponding actuation commands. In addition to being activated and deactivated, the lamp 50E can be configured to be intermittently activated in a predetermined pattern or so that the light intensity is varied in multiple steps. In such cases, the lamp 50E can be configured to change actuation states whenever receiving an actuation command or change actuation states in response to corresponding actuation commands.

The adjustable seatpost 50F is attached to the seatpost 26. The adjustable seatpost 50F lowers and raises the seatpost 26 relative to the frame 20. The energy converter 54F of the adjustable seatpost 50F includes an electric actuator or an electric motor. The adjustable seatpost 50F includes a telescopic electric seatpost that is extended and retracted by the force of an electric motor or a mechanical seatpost that is extended by the force of at least one of a spring and air and retracted manually. The mechanical seat position includes a hydraulic seatpost or a hydraulic and pneumatic seatpost. In the case of an electric seatpost, the electronic controller 52F of the adjustable seatpost 50F actuates the energy converter 54F, if operable, and extends or retracts the seatpost if the wireless communicator 56F receives an actuation command. In the case of an electric seatpost, the raising and lowering of the seatpost are performed by separate actuation commands. In the mechanical seatpost, the energy converter 54F controls a valve that opens and closes a flow path of oil or air. In the case of a mechanical seatpost, the electronic controller 52F of the adjustable seatpost 50F actuates the energy converter 54F and opens the valve if the wireless communicator 56F receives an actuation command. In a state in which the valve is open, the force of at least one of a spring and air acts to extend the adjustable seatpost 50F. In a state in which the valve is closed, the length of the adjustable seatpost 50F does not change. In the case of a mechanical seatpost, the valve can open for a predetermined time if an actuation command is received. Alternatively, if an actuation command is received, the valve can be kept open until the next actuation command is received.

The suspension 50G is arranged on the front fork 22 and attenuates the impact applied to the front wheel 12. The suspension 50G is switchable between a lock state, in which the function of the suspension 50G is restricted with the energy converter 54G, and an unlock state, in which the function of the suspension 50G is not restricted. The suspension 50G can be arranged on the frame 20 and be configured to attenuate the impact applied to the rear wheel 14. The suspension 50G can be any one of a hydraulic suspension, a pneumatic suspension, or a hybrid suspension that uses both hydraulic and pneumatic pressure. The energy converter 54G of the suspension 50G includes an electric actuator or an electric motor. The energy converter 54G controls a valve that opens and closes a flow path of oil or air. The electronic controller 52G of the suspension 50G actuates the energy converter 54G, if actuation is possible, and switches between the lock state and the unlock state if the wireless communicator 56G receives an actuation command. The suspension 50G can be configured to switch between the lock state and the unlock state whenever receiving an actuation command or switch between the lock state and the unlock state in response to corresponding actuation commands. In addition to the lock state and the unlock state, the suspension 50G can be configured to vary the attenuation force in multiple steps. In this case, whenever receiving an actuation command that differs from the actuation commands for switching between the lock state and the unlock state, the attenuation force can be switched one step at a time.

The drive unit 50H assists the propulsion of the bicycle 10. The electronic controller 52H of the drive unit 50H includes a drive circuit that drives the energy converter 54H. The energy converter 54H of the drive unit 50H includes an electric motor. The drive circuit controls the power supplied from the battery 42A to the electric motor. In the present embodiment, the electric motor transmits drive force to a power transmission path of manual drive force extending from the crankshaft 38 to the front rotor 32. In a configuration in which the drive unit 50H does not support the crank 28, the crank 28 is supported by the frame 20. Further, the electric motor of the drive unit 50H is arranged on the frame 20 of the bicycle 10, the rear wheel 14, or the front wheel 12. The electric motor of the drive unit 50H is configured to transmit rotation force to the front wheel 12 or to a transmission path of manual drive force extending from the pedals 30 to the rear wheel 14. Preferably, a power transmission force extending between the electric motor and the crankshaft 38 includes a one-way clutch (not shown) so that the rotation force of the crank 28 does not act on the electric motor in a case in which the crankshaft 38 rotates in a direction in which the bicycle 10 moves forward. The drive unit 50H includes the wireless communicator 56H, the electronic controller 52H, and the energy converter 54H. Additionally, the drive unit 50H includes, for example, a reduction gear that reduces the speed of the rotation generated by the electric motor and a torque sensor that detects the torque applied to the crank 28. The drive unit 50H can further include a rotation detection sensor that detects the rotation of the crank 28. The electronic controller 52H drives the electric motor in accordance with the detection result of the torque sensor. The electronic controller 52H of the drive unit 50H switches the actuation state of the energy converter 54H if the wireless communicator 56H receives an actuation command. The electronic controller 52H can actuate the energy converter 54H in multiple actuation modes having different assist ratios. The drive unit 50H switches actuation modes in accordance with actuation commands. The drive unit 50H can be configured to sequentially switch actuation modes whenever receiving an actuation command or switch actuation modes in accordance with an actuation command that increases the assist ratio and an actuation command that decreases the assist ratio. The actuation mode of the drive unit 50H can include a mode in which the motor does not provide assistance.

The operation portions 84 include a first operation portion 84A, a second operation portion 84B, and a third operation portion 84C. Preferably, the first operation portion 84A is arranged at the top of a free end of the base 78A. Preferably, the second operation portion 84B and the third operation portion 84C are arranged adjacent to the brake lever 78B. The locations of the operation portions 84 are not limited to such positions. There can be only one operation portion 84. Alternatively, there can be three or more operation portions 84. In one example, each operation portion 84 includes a lever or a button. The operation device 78 is electrically connected to the transmission device 80 by a power line L. In the present embodiment, the operation device 78 and the transmission device 80 are configured to perform Power Line Communication (PLC). The operation device 78 and the transmission device 80 each include a communication circuit to perform Power Line Communication. A port is provided on the base 78A. The power line L is connected in an attachable and removable manner to the port.

If the first operation portion 84A is operated in accordance with a first operation method, then the operation device 78 outputs a first operation signal to the transmission device 80. If the first operation portion 84A is operated in accordance with a second operation method, then the operation device 78 outputs a second operation signal to the transmission device 80. If the first operation portion 84A is operated in accordance with a third operation method, then the operation device 78 outputs a third operation signal to the transmission device 80. The first to third operation methods correspond to, for example, one of a short push, a long push, and a double click. A short push corresponds to a single push of the operation portion 84 within a predetermined period. A long push corresponds to pushing of the operation portion 84 for a predetermined period or longer. A double click corresponds to an operation in which the operation portion 84 is pushed twice during a predetermined period. In one example, the first operation portion 84A, the second operation portion 84B, and the third operation portion 84C each include a switch circuit. The operation device 78 further includes an electronic controller 79. The electronic controller 79 includes a detection circuit that detects the voltage output from the switch circuit.

For example, the memory device can be nonvolatile memory and volatile memory, and can includes a ROM (Read Only Memory) device, a RAM (Random Access Memory) device, a hard disk, a flash drive, etc. For example, if the first operation portion 84A is operated, then the switch circuit of the first operation portion 84A outputs a high-level voltage. If the first operation portion 84A is released, then the switch circuit of the first operation portion 84A outputs a low-level voltage. If the first operation portion 84A is operated, then the electronic controller 79 combines identification information corresponding to the operation device 78 and the first operation portion 84A with type information that is obtained by converting the voltage output from the switch circuit and indicates the type of the operation to generate the first to third operation signals and output the first to third operation signals to the transmission device 80. For example, the duration time of the high-level voltage or the low-level voltage and the number of times the high-level voltage or the low-level voltage has been detected are referred to in order to distinguish the first to third operation methods that the first operation portion 84A has undergone.

If the second operation portion 84B is operated in accordance with a fourth operation, then the operation device 78 outputs a fourth operation signal to the transmission device 80. If the second operation portion 84B is operated in accordance with a fifth operation, then the operation device 78 outputs a fifth operation signal to the transmission device 80. If the second operation portion 84B is operated in accordance with a sixth operation method, then the operation device 78 outputs a sixth operation signal to the transmission device 80. The fourth to sixth operation methods correspond to, for example, one of a short push, a long push, and a double click. For example, if the second operation portion 84B is operated, then the switch circuit of the second operation portion 84B outputs a high-level voltage. If the second operation portion 84B is released, then the switch circuit of the second operation portion 84B outputs a low-level voltage. If the second operation portion 84B is operated, then the electronic controller 79 combines identification information corresponding to the operation device 78 and the second operation portion 84B with type information output from the switch circuit to generate the fourth to sixth operation signals and output the fourth to sixth operation signals to the transmission device 80.

If the third operation portion 84C is operated in accordance with a seventh operation method, then the operation device 78 outputs a seventh operation signal to the transmission device 80. If the third operation portion 84C is operated in accordance with an eighth operation method, then the operation device 78 outputs an eighth operation signal to the transmission device 80. If the third operation portion 84C is operated in accordance with a ninth operation method, then the operation device 78 outputs a ninth operation signal to the transmission device 80. The seventh to ninth operation methods correspond to, for example, one of a short push, a long push, and a double click. For example, if the third operation portion 84C is operated, then the switch circuit of the third operation portion 84C outputs a high-level voltage. If the third operation portion 84C is released, then the switch circuit of the third operation portion 84C outputs a low-level voltage. If the third operation portion 84C is operated, then the electronic controller 79 combines identification information corresponding to the operation device 78 and the third operation portion 84C with type information output from the switch circuit to generate the seventh to ninth operation signals and output the seventh to ninth operation signals to the transmission device 80.

The identification information includes information that allows the electronic controller 86 and the user to identify the operation device 78 and the operation portions 84 such as the name or product number of the operation device 78 and the operation portions 84. The transmission device 80 is set so that whether or not operation information is transmitted depends on the operation signal. The electronic controller 86 includes a setting memory. The setting memory includes a non-volatile memory. The electronic controller 86 generates operation information if the information included in the input operation signal is stored in the setting memory and transmits the operation information to the second wireless transmitter 76 through wireless communication. In the present embodiment, the setting memory stores the identification information of the operation device 78 and the operation portions 84. When there is only one operation portion 84, the setting memory can store only the identification information of the operation device. When there is only one operation device 78, the setting memory can store only the identification information of the operation portions 84.

Table 1 indicates setting information stored in the setting memory. For example, the setting memory can store four pieces of setting information. In table 1, as setting number 1, for example, the setting memory stores the identification information of the first operation portion 84A of the operation device 78 shown in FIG. 2. As setting number 2, for example, the setting memory stores the identification information of the second operation portion 84B of the operation device 78 shown in FIG. 2. Setting numbers 3 and 4 has no settings. The number of settings that can be stored can be changed in accordance with the capacity of the setting memory. For example, the setting memory can be configured to store only one piece of setting information.

In step S12, the electronic controller 86 determines whether or not the identification signal included in the obtained operation signal matches the identification information stored in the setting memory. If the electronic controller 86 determines in step S12 that the identification signal included in the obtained operation signal matches the identification information stored in the setting memory, then the electronic controller 86 proceeds to step S13. If the electronic controller 86 determines in step S12 that the identification signal included in the obtained operation signal does not match the identification information stored in the setting memory, then the electronic controller 86 proceeds to step S11 after a predetermined cycle. In step S13, the electronic controller 86 generates operation information corresponding to the operation signal and proceeds to step S14. In step S14, the electronic controller 86 transmits the generated operation information from the second wireless transmitter 76 through wireless communication and proceeds to step S11 after a predetermined cycle. When the supply of power is stopped, the electronic controller 86 ends the processing.

The setting information stored in the setting memory can be changed using an external device P. The external device P includes, for example, one of a personal computer and a portable terminal such as a personal computer and a smartphone. The external device P and the transmission device 80 can be wire-connected by the power line L, which is connected in an attachable and removable manner to the port of the case 80A. Alternatively, the external device P and the transmission device 80 can be wireless-connected by the second wireless transmitter 76. The second wireless transmitter 76 can be configured as a wireless communication unit that receives information through wireless communication in addition to transmitting information through wireless communication.

The transmission device 80 transmits first operation information to transmit operation information corresponding to the first operation signal. The transmission device 80 transmits second operation information to transmit operation information corresponding to the second operation signal. The transmission device 80 transmits third operation information to transmit operation information corresponding to the third operation signal. The transmission device 80 transmits fourth operation information to transmit operation information corresponding to the fourth operation signal. The transmission device 80 transmits fifth operation information to transmit operation information corresponding to the fifth operation signal. The transmission device 80 transmits sixth operation information to transmit operation information corresponding to the sixth operation signal. The transmission device 80 transmits seventh operation information to transmit operation information corresponding to the seventh operation signal. The transmission device 80 transmits eighth operation information to transmit operation information corresponding to the eighth operation signal. The transmission device 80 transmits ninth operation information to transmit operation information corresponding to the ninth operation signal.

Preferably, as shown in FIG. 1, the electronic device body 82 is attached to the handlebar 24. As shown in FIG. 3, the electronic device body 82 includes the receiver 62, the first wireless transmitter 64, the memory device 66, the electronic controller 68, the housing 70 (refer to FIG. 2), the operation input portion 72 and the presentation device 74. The receiver 62, the first wireless transmitter 64, the memory device 66 and the electronic controller 68 are separate from the operation device 78. The receiver 62, the first wireless transmitter 64, the memory device 66, the electronic controller 68, the operation input portion 72 and the presentation device 74 are provided on the housing 70. The receiver 62, the first wireless transmitter 64, the memory device 66 and the electronic controller 68 are accommodated inside the housing 70 shown in FIG. 2. The operation input portion 72 and the presentation device 74 are provided on the housing 70 so as to be partially exposed to the outside of the housing 70. The electronic device body 82 includes a battery (not shown) and is not supplied with power from the battery unit 42. The electronic device body 82 can be configured by, for example, a cycle computer or a smartphone.

The receiver 62 shown in FIG. 3 receives operation information that corresponds to the operation of the operation device 78. The receiver 62 receives operation information that differs between the operation portions 84 that are operated. Further, the receiver 62 receives operation information that differs between the operation methods of the operation device 78. The receiver 62 receives the operation information through wireless communication. More specifically, the receiver 62 is configured to be able to receive operation information transmitted through wireless communication by the second wireless transmitter 76. If the receiver 62 receives operation information, the receiver 62 outputs the received operation information to the electronic controller 68. One example of the standard of the wireless communication performed by the second wireless transmitter 76 and the receiver 62 is ANT+ (registered trademark) or BLUETOOTH (registered trademark).

Preferably, the transmission device 80 and the electronic device body 82 are wireless-connected through pairing. As the transmission device 80 and the electronic device body 82 undergo pairing, the transmission device 80 transmits the identification information of the operation device 78 and the operation portions 84 stored in the setting memory and the type information corresponding to each piece of identification information of the operation portion 84 to the electronic device body 82.

The memory device 66 stores various types of control programs and information used for various types of control processes. The memory device 66 includes, for example, a non-volatile memory and a volatile memory and can includes a ROM (Read Only Memory) device, a RAM (Random Access Memory) device, a hard disk, a flash drive, etc. The memory device 66 is any computer storage device or any computer readable medium with the sole exception of a transitory, propagating signal. As the electronic device body 82 undergoes pairing with the transmission device 80, the electronic device body 82 stores the identification information and type information transmitted from the transmission device 80 in the memory device 66. This allows the electronic device body 82 to acknowledge the combination of the identification information and the type information that can be received from the transmission device 80. Table 2 shows one example of the information stored in the memory device 66 through pairing. For example, if the transmission device 80, which is connected to the operation device 78 shown in FIG. 2, is paired with the electronic device body 82, then the combinations of the identification information of the operation device 78 and the operation portions 84 shown in FIG. 2 and the operation methods that can be performed on the operation portions 84 are stored in the memory device 66.

TABLE 2 Identification Information of Operation Device and Operation Portions Operation Type 1st Operation Portion of Operation 1st Operation Method, 2nd Device Operation Method, 3rd Operation Method 2nd Operation Portion of Operation 1st Operation Method, 2nd Device Operation Method, 3rd Operation Method

The memory device 66 stores actuation commands, which are sent to the bicycle components 50, in correspondence with the operation information. The receiver 62 can receive multiple types of operation information. The memory device 66 stores actuation commands corresponding to the operation information. The actuation commands include identification information of the bicycle components 50 and information related to the actuation of the bicycle components 50.

Table 3 shows one example of actuation commands A to L that can be stored in the memory device 66. The bicycle component 50 that receives an actuation command including its identification information is actuated in accordance with the actuation command. If the bicycle component 50 is configured to be actuated in multiple steps, then the bicycle component 50 that receives the actuation command performs an actuation action one step at a time. If the bicycle component 50 cannot be actuated in accordance with the actuation command, then the bicycle component 50 is not actuated. If the drive unit 50H receives actuation command K in an assist OFF state, then the drive unit 50H starts assistance. If the drive unit 50H receives actuation command L in a state in which assistance is the weakest, then the drive unit 50H stops assistance. The transmission device 80 transmits actuation commands E and F in predetermined intervals during periods in which the front brake device 50C and the rear brake device 50D are operated, respectively. With regard to actuation commands E and F, if the brake devices 50C and 50D respectively receive actuation commands E and F, then the brake devices 50C and 50D continue to perform braking for a predetermined period from when the operation signal is received. If the lamp 50E receives actuation command G in an activated state, then the lamp 50E is switched OFF. If the lamp 50E receives actuation command G in a deactivated state, then the lamp 50E is switched ON. If the suspension 50G receives actuation command J in a locked state, then the suspension 50G switches to an unlocked state. If the suspension 50G receives actuation command J in an unlocked state, then the suspension 50G switches to a locked state. The actuation command corresponding to each bicycle component 50 can be added to the memory device 66 by pairing the electronic device 60 and the bicycle component 50.

The memory device 66 is configured to be able to change the actuation commands stored in correspondence with operation information. Table 4 is stored in the memory device 66 and shows the corresponding relationship of the operation information and the actuation commands.

TABLE 4 Operation Information Actuation command No Setting A No Setting B No Setting C No Setting D No Setting E No Setting F 1st Operation Information G No Setting H No Setting I 2nd Operation Information J No Setting K No Setting L

To change an actuation command that is stored in correspondence with operation information, the memory device 66 is configured to allow an actuation command to be changed in order to control a bicycle component 50 of a type that differs from the bicycle component 50 controlled in accordance with an actuation command prior to the change. For example, actuation command G corresponding to the first operation information in table 4 is changed to actuation command H to change the bicycle component 50 that is changed when receiving the first operation from the lamp 50E to the suspension 50G. The memory device 66 is configured to allow an actuation command, which corresponds to operation information, to be changed in accordance with information input from the external device P. The external device P and the electronic device body 82 are configured to be connectable through the receiver 62, the first wireless transmitter 64, or a cable. The receiver 62 can be configured as a wireless communication unit that transmits information through wireless communication in addition to receiving information through wireless communication. If the electronic device body 82 and the external device P are connected by a cable, then the electronic device body 82 further includes an external connection terminal such as a USB port.

The electronic controller 68 includes an arithmetic processing device that performs a predetermined control program. The arithmetic processing device includes, for example, a CPU or an MPU. The electronic controller 68 can include one or more arithmetic processing devices. If the receiver 62 receives operation information, then the electronic controller 68 transmits an actuation command that corresponds to the received operation information from the first wireless transmitter 64.

The operation performed by the electronic controller 68 of the electronic device body 82 will now be described with reference to FIG. 5. The electronic controller 68 executes this process in predetermined cycles as long as the electronic device body 82 is supplied with power. If the power supply of the electronic device body 82 goes ON, in step S21, then the electronic controller 68 determines whether or not operation information has been obtained. The power supply of the electronic device body 82 can be configured to be switchable between ON and OFF by a switch provided on the electronic device body 82. If the electronic controller 68 determines in step S21 that operation information has been obtained, then the electronic controller 68 proceeds to step S22. The electronic controller 68 repeats step S21 until determining that operation information has been obtained. In step S22, the electronic controller 68 determines whether or not the identification information included in the obtained operation information matches the identification information stored in the memory device 66. If the electronic controller 68 determines in step S22 that the identification information included in the obtained operation information matches the identification information stored in the memory device 66, then the electronic controller 68 proceeds to step S23. If the electronic controller 68 determines in step S22 that the identification information included in the obtained operation information does not match the identification information stored in the memory device 66, then the electronic controller 68 proceeds to step S21 after a predetermined cycle. In step S23, the electronic controller 68 reads the actuation command corresponding to the operation information from the memory device 66 and proceeds to step S24. In step S24, the electronic controller 68 transmits the read actuation command from the first wireless transmitter 64 through wireless communication and then proceeds to step S21 after a predetermined cycle. If the supply of power is cut, then the electronic controller 68 ends the processing.

The electronic controller 68 is configured to be able to change an actuation command, which is stored in correspondence with operation information in the memory device 66, in accordance with the operation of the operation input portion 72. One example of the standard of the wireless communication performed by the first wireless transmitter 64 and the wireless communicator 56 of each bicycle component 50 is ANT+ (registered trademark) or BLUETOOTH (registered trademark).

The operation input portion 72 is operable by the user. In one example, the operation input portion 72 is a button. The presentation device 74 is configured to present various types of information related to the bicycle 10. Various types of information related to the bicycle 10 includes information related to vehicle speed, information related to cadence, information related to heart rate, information related to travel distance, and the like. The operation input portion 72 is operated to change the information presented on the presentation device 74 with the electronic controller 68. The presentation device 74 is configured to present the information of the bicycle components 50 that are controlled in accordance with the operation of the operation device 78. The presentation device 74 includes at least one of a display panel and a speaker. The display panel includes, for example, a liquid crystal display panel or an organic electroluminescence (EL) display panel.

FIG. 6 shows one example of the information presented by the presentation device 74. The presentation device 74 shows a list of identification information related to the operation device 78 (name, product number, etc.), information related to the first operation portion 84A (name), type information indicating the type of operation method, identification information related to the bicycle components 50 (name, product number, etc.), and actuation actions of the bicycle components 50. Preferably, the identification information presented by the presentation device 74 is text information that can be intuitively acknowledged by the user. The information shown in FIG. 6 can be displayed on the presentation device 74 by performing a predetermined operation on the operation input portion 72. The display of the information shown in FIG. 6 on the presentation device 74 allows the user to acknowledge how to operate an operation portion 84 of the operation device 78 in order to actuate a bicycle component 50 in a certain manner. In the example shown in FIG. 6, the user can acknowledge that the lamp 50E can be activated or deactivated if the first operation portion 84A of the operation device 78 shown in FIG. 2 is operated in accordance with the first operation method. The user can also acknowledge that the suspension 50G can be switched between a lock state and an unlock state if the first operation portion 84A is operated in accordance with the second operation method. Further, the user can acknowledge that none of the bicycle components 50 are actuated if the first operation portion 84A is operated in accordance with the third operation method.

A method for controlling the electronic device 60 includes a first step, a second step, and a third step. The first step includes receiving operation information that corresponds to the operation of the operation device 78. The second step includes, when receiving operation information, transmitting an actuation command stored in correspondence with the received operation information through wireless communication. The third step includes changing an actuation command stored in correspondence with operation information. In one example, the first step is executed by the receiver 62, the second step is executed by the electronic controller 68, and the third step is executed by the electronic controller 68 or the external device P.

The process from the operation of the operation device 78 to the actuation of the bicycle components 50 will now be described. In accordance with the operation portion 84 that is operated and the operation content input to the operation portion 84, the operation device 78 transmits an operation signal to the transmission device 80. The transmission device 80 that receives the operation signal generates operation information corresponding to the operation signal and transmits the operation information to the electronic device body 82 through wireless communication. The electronic controller 68 of the electronic device body 82 that receives the operation information reads the actuation command corresponding to the operation information from the memory device 66 and transmits the actuation command to the bicycle components 50. Upon receipt of the actuation command, each bicycle component 50 determines whether or not the received actuation command includes its identification information. If the received actuation command does not include its identification information, then the bicycle component 50 is not actuated. If the received actuation command includes its identification information, then the bicycle component 50 is actuated in accordance with the actuation command.

The electronic controller 68 is operated in a normal mode and a setting changing mode. A predetermined operation is performed on the operation input portion 72 to shift from the normal mode to the setting changing mode. In the normal mode, the electronic controller 68 shows at least one of the various types of information of the bicycle 10 and transmits the actuation command corresponding to the received operation information from the first wireless transmitter 64. In the setting changing mode, the electronic controller 68 is able to change actuation commands that are stored in the memory device 66 in correspondence with operation information.

The process executed by the electronic controller 68 to change an actuation command that is stored in the memory device 66 in correspondence with operation information will now be described with reference to FIG. 8. The electronic controller 68 executes the process shown in FIG. 8 as long as the electronic controller 68 remains in the setting changing mode. The electronic controller 68 can end the setting changing mode if a predetermined operation is performed on the operation input portion 72 even while executing the process of FIG. 8.

If the electronic controller 68 enters the setting changing mode, in step S31, then the electronic controller 68 shows the present setting information on the presentation device 74 like in FIG. 6. The electronic controller 68 then proceeds to step S32. In step S32, the electronic controller 68 determines whether or not a change command has been received from the operation input portion 72. The electronic controller 68 determines that a change command has been received from the operation input portion 72 if, for example, the user uses the operation input portion 72 to indicate the setting that the user wishes to change with a cursor and then operates the operation input portion 72. If the electronic controller 68 determines in step S32 that a change command has been received, then the electronic controller 68 proceeds to step S33.

In step S33, the electronic controller 68 shows the changeable actuation commands on the presentation device 74 and then proceeds to step S34. For example, the electronic controller 68 shows the changeable actuation commands on the presentation device 74 in a manner allowing the changeable actuation commands to be pulled down for selection. The actuation commands include the identification information and actuation information of the bicycle components 50.

In step S34, the electronic controller 68 selects the actuation command that corresponds to the operation of the operation input portion 72 and determines whether or not a command determining the change has been input. If the electronic controller 68 determines that a command determining the change has been input, then the electronic controller 68 proceeds to step S35 and stores the changed information in the memory device 66. When step S35 ends, the electronic controller 68 proceeds to step S31 after a predetermined cycle.

If the electronic controller 68 determines in step S32 that there is no change command, then the electronic controller 68 proceeds to step S36. In step S36, the electronic controller 68 determines whether or not a predetermined period has elapsed. If the predetermined has not elapsed, then the electronic controller 68 proceeds to step S32. If the electronic controller 68 determines that the predetermined period has elapsed in step S36, then the electronic controller 68 proceeds to step S37. In step S37, the electronic controller 68 shifts to the normal mode and ends the process.

Second Embodiment

A second embodiment will now be described with reference to FIG. 9. In an electronic device 60A of the second embodiment, same reference numerals are given to those components that are the same as the corresponding components of the electronic device 60 of the first embodiment. The description will focus on parts differing from the electronic device 60 of the first embodiment.

As shown in FIG. 9, the operation device 78 of the electronic device 60A is connected to the first and second shifting devices 50A and 50B by the power line L. Each of the first and second shifting devices 50A and 50B does not include the wireless communicator 56 and includes a connection port that is connectable to the power line L. The operation device 78, the transmission device 80, the first and second shifting devices 50A and 50B and the drive unit 50H are configured to perform power line communication. The brake devices 50C and 50D include mechanical brake devices that are driven only by wires.

The setting information stored in the setting memory of the electronic controller 86 further includes actuation commands and information of the first and second shifting devices 50A and 50B and the drive unit 50H that are actuated in accordance with the operation of the operation portions 84 of the operation device 78. The setting information is shared by the first and second shifting devices 50A and 50B and the drive unit 50H. Upon receipt of operation signals that are stored in the setting information, the first and second shifting devices 50A and 50B and the drive unit 50H are actuated in accordance with the actuation command stored in the setting information. The setting memory does not have to be provided on the electronic controller 86 and can be separate from the transmission device 80. As long as the setting memory can be referred to by the electronic controller 86, the setting memory can be provided on any of the operation device 78, the first and second shifting devices 50A and 50B, the drive unit 50H, and the battery unit 42. Further, the setting memory can be arranged separately from the operation device 78, the first and second shifting devices 50A and 50B, the drive unit 50H, and the battery unit 42. Table 5 is a chart showing an example of the setting information stored in the setting memory. For example, the setting memory can store four pieces of setting information in correspondence with the transmission device 80. The setting memory can store, for example, the identification information of the transmission device 80 in correspondence with the four operation portions 84. In the example shown in table 5, the identification information of the transmission device 80 and setting number 1 are stored in correspondence with the identification information of the first operation portion 84A of the operation device 78. The setting number does not have to be stored. However, if the number that can be set is determined, it is preferred that the number be stored so that it can be displayed. The identification information of the transmission device 80 can also be stored in correspondence with the three operation portions 84. However, such identification information is not set in the example of table 5. The number of pieces of setting information stored in correspondence with the transmission device 80 can be changed in accordance with the capacity of the setting memory.

The operation device 78 includes a shifter that actuates the shifting devices 50A and 50B. The operation device 78 further includes a fourth operation portion 84D and a fifth operation portion 84E. The fourth operation portion 84D and the fifth operation portion 84E can be arranged on the base 78A or on a base that is separate from the base 78A. The fourth operation portion 84D and the fifth operation portion 84E are configured in the same manner as the first operation portion 84A, second operation portion 84B, and the third operation portion 84C. If the fourth operation portion 84D is operated, then the electronic controller 79 combines the identification information corresponding to the operation device 78 and the fourth operation portion 84D with type information converted from the voltage output from a switch circuit indicating the type of operation to generate a tenth operation signal. The electronic controller 79 then outputs the tenth operation signal to the transmission device 80. If the fifth operation portion 84E is operated, the electronic controller 79 combines identification information corresponding to the operation device 78 and the fifth operation portion 84E with type information converted from the voltage output from a switch circuit indicating the type of operation to generate an eleventh operation signal. The electronic controller 79 then outputs the eleventh operation signal to the transmission device 80.

The process executed by the electronic controller 86 of the transmission device 80 is similar to the flowchart of FIG. 4 and differs only in the processing of step S12. In step S12, the electronic controller 86 determines whether or not the identification information included in the obtained operation signal matches the identification information stored in correspondence with the transmission device 80. If the electronic controller 86 determines that the identification information included in the obtained operation signal matches the identification information stored in correspondence with the transmission device 80, then the electronic controller 86 proceeds to step S13. If the electronic controller 86 determines that the identification information included in the obtained operation signal does not match the identification information stored in correspondence with the transmission device 80, then the electronic controller 86 proceeds to step 11.

The processing order for changing the setting information stored in the setting memory of the electronic controller 86 with the external device P will now be described with reference to FIGS. 10 and 11. In a state in which the external device P is connected to the electronic device 60A, if a request for reading the setting information is input to an input portion of the external device P, the external device P transmits the setting information read request to the electronic device 60A. The electronic device 60A reads the setting information from the setting memory and transmits the setting information to the external device P. The external device P shows a setting screen on a display PM of the external device P based on the received setting information.

FIG. 10 shows one example of a setting screen shown in the display PM of the external device P. In FIG. 10, if the setting screen for the second operation portion 84B of the operation device 78 is displayed, a mark (black circle in FIGS. 10 and 11) is shown to indicate that shift-up of the first shifting device 50A has been selected. The setting screen shows items that can be set in correspondence with the second operation portion 84B of the operation device 78. If the shifting devices 50A and 50B can be actuated by operating the second operation portion 84B of the operation device 78, then shifting items are shown on the setting screen. If operation information can be transmitted from the transmission device 80 by operating the second operation portion 84B of the operation device 78, then items of the transmission device 80 are shown on the setting screen. For example, if shifting items is selected from the setting screen, then the items that are shown can be shift-up of the first shifting device 50A, shift-down of the first shifting device 50A, shift-up of the second shifting device 50B, and shift-down of the second shifting device 50B. If the user wishes to change the setting information, then the user moves the black circle on the setting screen shown in FIG. 10 to another item with the input portion of the external device P.

For example, if the user operates the second operation portion 84B of the operation device 78 and wishes to transmit operation information from the transmission device 80, then the user operates the input portion of the external device P and selects the item of the transmission device shown in FIG. 10 to show setting numbers 1 to 4. Setting number 1 has already been set in correspondence with the first operation portion 84A of the operation device 78. Thus, setting number 1 is shown in a light color and cannot be selected. When setting the item of the transmission device 80, the display of the items corresponding to shifting items is closed. In FIG. 11, setting number 2 is marked by the black circle.

After changing the setting information on the setting screen, if a setting information change request is input to the input portion of the external device P, the external device P transmits changed setting information to the setting memory. The setting memory stores the changed setting information.

The setting information of the setting memory can be changed without using the external device P. In this case, for example, a display device is electrically connected to the operation device 78 and the transmission device 80 and the display device shows the setting information. The setting screens shown in FIGS. 10 and 11 are displayed on the display device, and the operation device 78 is used to change the setting information.

An electronic device 60B of a third embodiment will now be described with reference to FIGS. 2 and 12. Same reference numerals are given to those components that are the same as the corresponding components of the first embodiment. The description will focus on parts differing from the first embodiment. In the electronic device 60B of the third embodiment, the electronic device body 82 of the electronic device 60 is incorporated in the operation device 78. The electronic controller 79 and the transmission device 80 are omitted from the electronic device 60.

As shown in FIG. 12, the receiver 62, the first wireless transmitter 64, the memory device 66 and the electronic controller 68 are provided on the operation device 78. The receiver 62, the first wireless transmitter 64, the memory device 66 and the electronic controller 68 are arranged on the base 78A (refer to FIG. 2) of the operation device 78.

The operation portions 84 are wire-connected to the receiver 62. Operation of each operation portion 84 transmits an operation signal to the receiver 62. The receiver 62 obtains operation information from the received operation signal. If the receiver 62 receives the operation signal, then the electronic controller 68 reads an actuation command that corresponds to the operation information from the memory device 66 and transmits the actuation command from the first wireless transmitter 64. The electronic device 60B can further include one of the presentation device 74 and the operation input portion 72 shown in FIG. 3. The presentation device 74 and the operation input portion 72 can be separate from the operation device 78.

Modifications

An electronic device and a method for controlling the electronic device according to the present invention are exemplified in each of the above embodiments. However, the present invention is not limited to the above embodiments. Particularly, it should be understood from this disclosure that the present invention can be modified as described below. Same reference numerals are given to those components that are the same as the corresponding components of the above embodiments. Such components will not be described in detail.

Multiple actuation commands can correspond to the same operation information. In this case, the memory device 66 stores the actuation commands that correspond to the operation information. If the receiver 62 receives operation information, then the electronic controller 68 reads the actuation commands corresponding to the operation information and transmits the actuation commands from the first wireless transmitter 64. As a result, the bicycle components 50 included in the actuation signal are actuated in accordance with the actuation signal or one of the bicycle components 50 perform multiple actuation actions. More specifically, in a case in which the first operation information corresponds to the switching of the suspension 50G to a locked state and the lifting of the seatpost 26 of the adjustable seatpost 50F, if the first operation method is performed on the first operation portion 84A, the suspension 50G is switched to the locked state and the seatpost 26 is lifted.

The electronic device 60 can control only one of the bicycle components 50. In this case, the memory device 66 stores only one actuation command. The electronic controller 68 or the external device P updates an actuation command stored in the memory device 66 and changes the stored actuation command in correspondence with the operation information. This changes the bicycle component 50 or the actuation action of the bicycle component 50 that is controlled by the electronic controller 68.

The electronic controller 68 can disable changing of an actuation command that corresponds to operation information and enable changing of an actuation command that corresponds to operation information with only the external device P. Further, the external device P can disable changing of an actuation command that corresponds to operation information and enable changing of an actuation command that corresponds to operation information with only the electronic controller 68.

The presentation device 74 can be omitted from the electronic device body 82 of the first and second embodiments. The operation device 78 and the transmission device 80 can be omitted from the electronic device 60. In this case, the electronic device 60 is configured by only the electronic device body 82. The operation device 78 can be omitted from the electronic device 60A of the second embodiment. In this case, the electronic device 60A is configured by the electronic device body 82 and the transmission device 80. In the electronic devices 60 and 60A of the first and second embodiments, the operation device 78 and the transmission device 80 can be formed integrally. In this case, the second wireless transmitter 76 and the electronic controller 86 are provided on the operation device 78.

One of the first shifting device 50A and the second shifting device 50B can be changed to an internal geared hub. The internal geared hub is arranged around the crankshaft 38 or in an axle hub of the rear wheel 14. The internal geared hub changes the coupled state of gears that configure a planetary gear mechanism inside the shifting device. The internal geared hub can include a Continuously Variable Transmission (CVT) mechanism. In one example, the CVT mechanism includes an input body, an output body, and a transmission body. The CVT mechanism rotates the transmission body to continuously vary the transmission ratio.

The setting memory can store the identification information of all of the operation device 78 and the operation portions 84 that are connected and the setting information indicating whether or not the operation information is transmitted in correspondence with the operation of the operation portions 84. Table 6 shows an example of the setting information stored in the setting memory. In this case, the electronic controller 86 compares the information included in the input operation signal with the setting information stored in the setting memory. If the setting indicates transmission of the operation information, then the operation information can be generated and transmitted from the second wireless transmitter 76 through wireless communication.
